SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill ensures that Docker Compose configurations for .NET projects are standardized, secure, and easy to manage, particularly concerning sensitive environment variables.

Core Features & Use Cases

  • Secret Management: Enforces the use of .env files for secrets and .env.example for documentation, ensuring sensitive data is never committed to version control.
  • ASP.NET Core Integration: Guides users on correctly injecting environment variables into .NET applications using the Section__Property convention, avoiding custom prefixes in code.
  • Use Case: You have a .NET application with database credentials and API keys that need to be configured in Docker Compose. This Skill helps you set up your docker-compose.yml, .env, and .env.example files correctly to manage these secrets securely and efficiently.

Quick Start

Use the docker-compose-config skill to standardize the Docker Compose configuration for a .NET project, ensuring secrets are managed via .env files and injected using the ASP.NET Core __ convention.

FAQPage Schema
How do I manage secrets in Docker Compose for a .NET application?▼

Docker Compose manages secrets for .NET applications by enforcing .env files for sensitive data and .env.example for documentation. It configures docker-compose.yml to map these variables into containers without custom code prefixes.

How do I inject environment variables into ASP.NET Core using Docker Compose?▼

Inject environment variables into ASP.NET Core using Docker Compose by applying the double-underscore convention (Section__Property). This maps Docker environment variables directly to application settings, avoiding the need for custom prefixes in your .NET code.

What is the ASP.NET Core double-underscore convention for environment variables?▼

The ASP.NET Core double-underscore convention is a mechanism for mapping environment variables to application settings hierarchies. It allows Docker Compose to inject configuration values directly into .NET projects without requiring custom code prefixes.

How do I prevent Docker Compose secrets from being committed to version control?▼

Prevent Docker Compose secrets from being committed to version control by storing sensitive data in .env files and adding them to .gitignore. Maintain an .env.example file in the repository to document required variables without exposing actual values.

Can I use Docker Compose configuration for .NET projects without custom environment variable prefixes?▼

Yes, you can configure Docker Compose for .NET projects without custom environment variable prefixes. By using the ASP.NET Core double-underscore convention, environment variables map directly to application settings, eliminating the need for custom prefix logic in code.
